This project was led with the French National Forestry Office (ONF), which is an institution responsible for the management of public forests, under the supervision of the Ministry of Agriculture and Food and the Ministry of Ecological Transition. Our common project has studied how to apply behavioral science to enhance user safety in forests. It resulted in the generation of 17 Nudges. Experimentation is expected to start spring 2022.

Farmers and the new green architecture of the EU common agricultural policy: a behavioural…
This behavioural experiment with farmers assessed the effect of two policy features of the new green architecture of the EU common agricultural policy on the adoption of environmentally friendly practices: (1) increasing mandatory adoption and (2) shifting budget to voluntary schemes, by decreasing direct payments.

Challenge
Students in low-income districts are less likely to sign up to take the Gifted and Talented (G&T) admissions test than their peers in higher-income districts. As a result, fewer students from low-income districts test into and attend G&T programs that could improve educational outcomes and provide meaningful opportunities. To the extent that the city may use sign-up rates as an indicator of demand, and thus where additional G&T programs should be located, low sign-up rates can mean…

Full price information for consumers: What effect does the way prices are displayed have on online…
The Netherlands Authority for Consumers & Markets (ACM) conducted an experiment to investigate the effect of incomplete prices when booking a holiday home. Websites that display incomplete prices cause greater uncertainty, make choosing more difficult, undermine trust and give the feeling of deception compared to websites displaying transparent prices.
Why this experiment was conducted: unclear picture of actual costs
In 2021, the ACM conducted a study into effective transparency. The aim was…
Landfills are a major contributor to methane emissions in the United States. By diverting organic waste from landfills, composting may reduce the global warming effects caused by methane. However, only a small proportion of compostable food is currently composted. This is because of barriers to composting that are both structural (lack of public composting infrastructure) and psychological (insufficient knowledge about and interest in composting among prospective users).
We set out to develop a…
Online experiment tested two novel public health messages on social distancing.
•Messages focused on potential to infect vulnerable people or many people.
•Participants (N = 500) randomized to see control or (one of two) treatment posters.
•Behavioral intentions and acceptability judgements of behaviors measured later.
•Both posters increased caution with respect to social distancing.

Website Verbeterjehuis.nl helps homeowners choose the right sustainability measures: which…
This online experiment tested various ways in which sustainability measures for homeowners are presented on the website verbeterjehuis.nl, ‘improve your home’. The variant emphasising that the sustainability measures are 'recommended for your personal situation' proved to be most effective. This addition acts as an incentive to homeowners to install roof insulation or adopt other sustainability measures.

In a pre-registered experiment, we tested whether expert endorsement increases the effectiveness of debunking messages about COVID-19 vaccines. We monitored a sample of 2,277 people in Italy through a longitudinal study along the salient phases of the vaccination campaign. Participants received a series of messages endorsed by either medical researchers (experimental group) or by generic others (control). In order to minimise demand effects, we collected participants’ responses always at ten…
